DISH-CLEANER.

SPECIFICATION forming partof Letters Patent No. 598,432, dated February1, 1898.

Application filed June 1, 1897- $eria1No 638,931. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM I. McOA s- LAND, a citizen of the UnitedStates, residing at Indianapolis, in the county of Marion and State ofIndiana, have invented certain new and useful Improvements inDish-Washing Machines, of which the following isa specification. 7

My present invention consists of certain im provements upon LettersPatent Nos. 377,765, 427,601, and 516,103 heretofore granted meonmachines of this same general character. A machine embodying saidimprovements will be first fully described, and said improvements thenparticularly pointed out in the claim.

Referring to the accompanying drawings, which are made a part hereof andon which similar letters and numerals of reference indicate similarparts, Figure 1 is a side elevation of a machine embodying my presentinvention; Fig. 2, an under side plan thereof; Fig. 3, a centralsectional view of the same; Fig. 4, a detail elevation of the drivingmechanism; and Fig. 5 a detail view, on an enlarged scale, of the valveto the discharge-pipe.

In said drawings the portions marked A represent the outer case B, theinner case or pan; 0, the perforated removable bottom to said inner caseof pan; D, a cover tothe machine, and E the water-wheel. These parts,generally speaking, correspond in their general features to those shownin my previouslyobtained Letters Patent above referred to, but areimproved in form and construction. The

parts A and B, however, are closely united at a by a Water-tight jointwithout the use of the various means which were described in said formerpatents. I prefer to screw-thread the adjacent portions of these partswhere they come together at this point and unite them by that means; butI have discovered by practical operation" of the machines that saidparts never need to be separated in use, and therefore they may besoldered tightly together, if desired.

The water-wheel E has a shaft 1, which is mounted in suitable bearingsin the frame F and in the base of the outer shell A, passing up towithin the machine through said lastnamed bearing, which has a stuffingbox 2 for the purpose of making it water-tight. Upon the lower end ofthis shaft is a spur-pinion 3, and a spur gear-wheel 4 is mounted onacounter-shaft 5 and engages therewith. This spur gear-wheel 4 has abevel-pinion on its hub, with which a bevel gear-wheel 6 on thecrankshaft 7 engages, said crank-shaft being driven by the usual crank8. By this means a very simple and effective multiplying-gear isproduced, arranged in proper relation to the machine, and thewater-wheel is driven therefrom without any part of said gearing passinginto the machine, where it would be in the way.

The discharge-pipe P is secured to the under side of the machine and isadapted to dis charge the water therefrom through its nozzle n. I haveprovided a peculiar valve, which is adapted to be moved extremelypromptly and at the same time can be quickly regulated in tension. Therod R, having a head 4", passes through a tube or sleeve T and has acombined pull and nut R upon the outer end. Interposed between the head'1' and the end of the tube T (or a washer t) is a section of rubbertubing V, constituting. the valve proper.

The perforation in the pipe P is of uniform diameter and extends on bothsides of the nozzle n. Ordinarily the discharge is controlled by pullingor pushing on the pull R, bringing the valve proper, V, to one side orthe other of the nozzle, as may bedesired, thus either shutting off theflow, as shown in Fig. 5, or permitting said flow when the Valve is onthe opposite side of the nozzle. In order to maintain this valvecontinuously in proper condition, (under all circumstances of hot andcold and soapy water,) it is necessary that it should be convenientlyadjustable. This is done by simply turning the pull R, (which, as beforestated, is also a Hill 1,) when the rubber portion V of the valve willbe compressed or loosened, as will be readily understood. I havetherefore provided an extremely simple, cheap, and effective valve forthis purpose. When the rubber portion V is worn out, by'renioving a capP the whole structure may be removed and a new piece of rubber inserted,which makes practically a new valve. While the valve thus described andshown in Fig. 5 is considered of peculiar fitness for the purpose, yet,as will be understood, otherforms may be used, if preferred, and I donot therefore make this a feature of this invention, but illustrate itin connection herewith in order that a most desirable form may be seen.

The operation of my machine maybe briefly described as follows: Dishesto be cleansed are placed within the inner receptacle or pan B, restingupon the perforated bottom 0. Water in suitable quantity and conditionis placed within the machine, the coverD placed on, and the crank orhandle 8 turned. This through the gearing described operates theWater-wheel E, which, by centrifugal force,

drives the water strongly and copiously through the perforations in theinner casing B onto the dishes being treated. It descends through theperforations in the false bottom 0 into the space where the water-wheelis and is thus continuously reused as long as desired. Water isdischarged by the manipulation of the valve V, heretofore described. Aswill be observed, there is no machinery within the washer to interferewith the proper handling of the dishes. The false bottom C is removableand is normally retained in place by the upper end of the shaft 1, whichprojects high enough to serve that purpose. The gearing, as I have foundby practical experience, is a great improvement on those formerly usedby me.

Having thus fully described my said inven- I tion, what I claim as new,and desire to secure by Letters Patent, is-

The combination, in a dish-washing machine having a double casing theinner one containing perforations through which the water may be forcedfrom the chamber between the two walls, of a water-wheel mounted betweensaid two walls, a shaft thereto extending through a stuffing-box tobelow the outer wall, a pinion on the lower end of said shaft, a spurgear-wheel mounted on a counter-shaft and engaging with said pinion andhaving a bevel-pinion on its hub, a drivingshaft mounted in suitablebearings and extending in horizontally across said countershaft andprovided with a bevel-gear on its inner end which engages with saidbevel-pinion on the hub of said spur gear-wheel, and a suitable crank onsaid driving-shaft for turning the same, all arranged and operatingsubstantially as set forth.

In witness whereof I have hereunto set my hand and seal, atIndianapolis,.Indiana, this 26th day of May, A. D. 1897.
